o/s pr3 pistons
shot peen ls rods
arp rod bolts,head studs
b16 head,valve train,cams
ge ls vtec kit
chiped pr3 obd1 ecu /crome
can anyone tell me about where in the rpm i will stop making power at????
i was thinking about 7,200rpm
i am going to upgrade cams shortly,but for now the b16 stockers will do.lol
car should be up and running early next week,it's a 92 integra,aem intake,dc sports header,lowered and gsr tranny. should work good anyway
thanks for any input or help
 
that all depends on the cams. not for nothing, but stock b16 cams make power up to 8k on stock ls/vtec engines. not much power though. if you plan on going with those pistons, use itr cams. they will make power all the way up to 9k no problems. my old old setup was similiar but with 12.5:1 compression and itr cams and it made power up to 8900 slightly falling off at 9000 rpm. most people wont spin ls/vtec's over 8k due to the long rod stroke. produces more torque but loses the reliability to spin high. I spun a bearing twice at 9k after 4 months of hardcore abuse on my old old setup, two different blocks. broken in properly on a dyno and all. now im experimenting with different cranks.
 
don't plan on spinning to 9,000rpm
8,000 should be fine when dynoed and camed
going to be my daily driver
 
i know this is alil bit old but

i dynoed my DA w/ a b16a and the power curve went all the way up to redline.
